Abstract (en)
[origin: EP2413584A1] Data of each plane capable of obtaining a high-quality output image is generated. An image processing apparatus (10) for quantizing input image data having gradation of an m value (m is a natural number) into output image data having gradation of an n value (n is a natural number smaller than m) includes quantization means configured to quantize input image data having gradation of an m value in a target pixel into output image data having gradation of an n value, and plane separation means configured to determine that the quantization value quantized by the quantization means is to be assigned to the target pixel of which plane out of planes of two types or more, wherein the plane separation means determines that the quantization value is to be assigned to the target pixel of which plane , based ondistanceinformationofthe target pixel indicating distances, to the target pixel, from pixels on which a recording material is recorded in the each plane.
